title: Repeated in vitro fertilization cycle attempts in patients undergoing controlled ovarian hyperstimulation with use of gonadotropin-releasing hormone antagonists.
abstract: To examine pregnancy rate in patients undergoing controlled ovarian hyperstimulation (COH) with use of multidose GnRH antagonists in multiple repeated IVF cycle attempts, we conducted a survey in 785 consecutive IVF cycles in our unit. Although pregnancy rate significantly decreased beyond the second IVF cycle attempt, no significant decrease was noted between cycle attempts 3 and 4 and 5 to 8.
